Different person but anyway. Well, in work I use a computer and it has a screen, so my existence is not at all without screens. Now, I communicate with family and friends in real life and sometimes in phone, my phone is very old and while it technically has a small non-touchscreen it's useless for anything other than brief SMS messages. I've got a computer also in my home but I don't use facebook or any chat programs, only a few anonymous niche sites comparable to hacker news to stay tuned to what's happening in the world and gather information of the topics I like. I would probably go insane if my family and friends were bombarding me with smalltalk all the time.

Zero notifications outside work hours, I'll check my email a few times a week if I'm not expecting anything. Life is good. I'd say the absolute majority of the information we receive is either non-important or outright harmful and it's beneficial to block as much as you can possibly can.

Not sure where I said I was screenless. However, I have no smartphone, no social media (apart from occasionally poking the HN bear), no personal laptop, no smart watch, etc.
